AN AMPLIFYING SYSTEM FOR A DENSE MEMORY ARRAY

A memory system is provided in which two load transistors (T3, T4) connected to a latch (T1, T2) forming a sense amplifier (10A) are individually controlled and connected to a common input/output line (I/O1) of a plurality of sense amplifiers (10A-H). Bit/sense lines (B/SL, B/SR) are connected to the two nodes (a, b) on the latch (T1, T2). By providing two such latches (T1, T2) each with bit/sense lines (B/SL, B/SR) and two individually controlled load devices (T3, T4) connected to the common input/output line (I/O1), two memory cells (C2, C3) of a word line (WL3 or WL4) may be sensed simultaneously.
